1899751 - In main window cannot use Ctrl-PageDown to switch to another tab

Status: NEW

(Thunderbird :: Mail Window Front End, defect)

Description

[Kai Engert [:KaiE:]]

Using TB 115, when in the mail main window, with additional tabs open (e.g. calendar or an open email in a tab),
I could use the keyboard shortcuts CTRL-PageDown or CTRL-PageUp to switch to one of the other open tabs.

This no longer works for me on Linux.
Instead, the shortcut scrolls the message list.

Interestingly, if the currently active tab is another tab (e.g. calendar or email open in a tab), the shortcut still works to cycle through open tabs (until I arrive at the main email hierarchy tab).

For what little it's worth, ctrl-pageup/down working fine for me on MacOS 13.6.7, Daily 0530.

Ironically, I wasn't aware of this shortcut; I'd always used ctrl-alt-arrow (cmd-opt-arrow on Mac), which is no longer working on Mac, see bug 1859927.

Instead, the shortcut scrolls the message list.

If I have focus on the message list then the shortcut will page down in the Message List.
If I select the eg: Inbox tab or select Inbox folder in Folder Pane and then use the Ctrl+page down shortcut, it selects the next tab.

So I'm assuming you have selected a email in list and therefore focus is currently on Message List.

[:Gijs (he/him)]

The change in bug 1753414 made it such that we check event.defaultPreventedByChrome before changing the tabbox selected tab based on a keyboard event. I would argue this is the correct behaviour; the bug is likely that something somewhere else is calling preventDefault without checking for modifier keys (ctrl, or meta on macOS) being pressed.

FWIW,
Workaround, Removing focus from the threadpane, then press Ctrl+PageUp/Down.
e.g,
1-a. Press Ctrl+K
1-b. Click Folder pane
1-c. Press F6 key
2. Then press Ctrl+PageUp/Down.

I confirm that it happens when the focus is on the message list, thanks a lot for the workarounds!
(very helpful for the meantime)

I would advise that you do not use 'Ctrl+Page Down' if you want to jump through opened tabs as it means you need to get focus in a specific area first.
I use 'Ctrl+Tab' and no matter what I'm currently focused on in Message List, the shortcut allows me to select the opened tabs.
Simple and efficient.

I wasn't aware of Ctrl-Tab, thanks.
